What is a directed line segment or vector

The video tutorial introduces vectors and directional line segments, explaining how they are defined by initial and terminal points, such as P and Q. It emphasizes the importance of direction and distance in defining these segments and introduces the concept of vectors as directional line segments on a plane. The tutorial also covers vector notation, using lowercase letters like V, U, and W, and explains vector equivalence based on having the same direction and magnitude.
